AUTOMATIC DlSlNFECTOR FOR FLUSHlNG-TANKS.

SPEClFICATION forming part of Letters Patent N 0. 685,020, dated October2, 190

Application filed April 5, 1901. Serial No. 54,566. (No model.)

T0 at whom it may concern:

Be it known that 1, JAMES HENRY VENNERS, a citizen of the United States,residing at Brooklyn, (post-offlce address 450 St. Marks avenue,) in thecounty of Kings and State of New York, have invented new and usefulImprovements in Automatic Disinfectors for Flushing-Tanks, of which thefollowing is a specification.

This invention relates to automatic disinfectors for flushing-tanks, theobject in View being to provide a device in the nature of a receptaclefor disinfecting material, the same being adapted to be applied to andused in connection with the usual overhead flushingtank and beingequipped with means influenced by the rise and fall of the water in thetank, whereby the water is admitted to the receptacle containing thedisinfecting material and ejected therefrom after taking up a portion ofthe disinfecting material, the water so ejected from the receptaclebeing mingled with the larger body of Water in the flushing-tank, fromwhich the Whole body of water is discharged through the usualflushing-tank in the ordinary manner.

With the above and other objects in view, the nature of which willappear more fully as the description proceeds, the invention consists inthe novel construction, combination,

and arrangement of parts hereinafter fully described, illustrated, andclaimed.

Fig. 4c is a sideelevation of a slightly-modified form of disinfector. Fig. 5 isavertical sectional view of the same. Figs. 6 and 7 illustrate amodified form of automatic disinfector in which the controlling float isarranged within the receptacle.

Similar numerals of reference designate corresponding parts in allfigures of the drawings.

For the purpose of illustration and to show the application of thepresent improvement I have illustrated in Fig. 1 an ordinary overheadflushing-tank, (designated by the numeral 1,) the same having connectedthere with the flushing-pipe 2, opened and closed by means of the usualvalve 3, having its stem 4 connected to an operating-lever 5, fulcrumedon a bracket 6 near one end of the tank. For controlling the supply ofwater to the tank the usual automatic float-valve 7 may be employed,operated through suitable connections by means of a float-ball 8,arranged within the tank and adapted to be raised and lowered by thewater, thereby operating the connections and opening or clos ,ing thevalve 7 to admit water to the tank make use'of a'receptacle 9, which forcon- .venienoe is shown of cylindrical form, al-

though it willbe understood that the receptacle may be of any size,shape, or configuration. Said receptacle is adapted to contain a supplyof disinfecting material, which is preferably in the form of crystals,which disinfecting material is arranged in the lower portion of thereceptacle, as shown in Fig. 3, and is covered by a perforated disk 10,which prevents the crystals from rising and floating about in the waterand which also acts in the nature of a strainer. The top of thereceptacle is covered by means of a lid 11, having an annular flange 12,which fits around the top of the receptacle, as shown in Figs. 2 and 3,which cover is provided with a number of openings or perforations 13 forthe passageof the water to and from the receptacle. The cover is alsoprovided with a central upward extension 14, forming a bearing for thestem 15 of a float 16, which is arranged above and outside of thereceptacle, so as tobe acted upon by the water in the tank only, asshown in Fig. 1. The stem 15 has connected to its lower end an agitatingdisk 17, which is adapted to move upward and downward within the upperportion of the receptacle under the influence of the water on float 16.

From the foregoing description it will be seen that a portion of thewater contained in the tank 1 will find its way through the openings13into the receptacle 9 and through the perforated disk or plat-e 10,where it will dissolve a portion of the crystals and take up asufficient proportion thereof to affect the whole body of water alreadyin the tank 1. \Vhen the water is exhausted from the'tank 1, the float16 descends and carries downward the disk or plate 17. As the waterrises in the tank lit lifts the float 16,and thereby elevates the disk17, which serves to agitate the water within 'the receptacle 9 and ejectthe same through the openings 13, thus causing the water which has takenup a considerable amount of the disinfecting material to mingle with thelarger body of water in the tank. In this way disinfecting material isautomatically supplied to the main body of water in the tank 1 duringthe operation of filling the tank.

In Figs. 4 and 5 I have shown a modified form of automatic disinfector,in which the main receptacle 9 is provided with an inner tube 18,depending from the top 19 and extending downward into the receptacle asuitable distance, where its lower end is closed, as shown at 20. Thetube 18 is provided near its lower end with perforations 21 for thepassage of water, and the upper end of the tube is partly closed bymeans of a perforated cover 22, having the openings 23 for the passageof water. Mounted to move vertically within the tube 18 is the disk orplate 24, which is connected to the lower end of the stem 25, carryingthe float 26 at its upper end. When the float 26 is in its lowestposition, as illustrated in Fig. 5, the disk 2% is beneath the openings21, thus allowing water to pass through the openings 23 and 21 into themain receptacle 9, where it acts upon the crystals of disinfectingmaterial. As the water rises in the tank and lifts the float 26 the disk24 is carried upward, thereby forcing the water ahead of it and outwardthrough the openings 23, where it iningles with the main body of waterin the tank 1. In principle the construction just referred to.ispractically the same as that above set forth and illustratedparticularly in Figs. 1 to 3, inclusive. It will thus be seen that theentire body of water in the tank 1 is affected by the disinfectingmaterial and that the water itself, by rising and falling within thetank, causes the disinfecting attachment to operate automatically, so

that only a certain proportion of disinfectingmaterial is taken up bythe water and delivered to the main body of water contained in the tank,thereby economizing in the use of the disinfecting material, while atthe same time affording a suflicient supply thereof to impart to thewhole body of water the requisite disinfecting properties.

In Figs. 6 and 7 I have illustrated a modified construction of automaticdisinfector, in which 27 designates the receptacle, which is shownrectangular in shape. The lower portion of the receptacle is designed tobe occupied by the crystals of disinfecting material, and said materialis covered by means of a perforated plate or disk 28, through which thewater is adapted to percolate. Within the upper portion of thereceptacle above the plate 28 is a rising and falling float 29, whichserves the double purpose of a float and an agitator and is limited inits upward movement by the top or cover 30 of the receptacle, the saidcover being provided with ventholes 31. The receptacle is provided insome or all of its sides with ports 32, through which the water lnaypassinto and out of the receptacles These port-holes are arranged just abovethe perforated plate 28 and above the level of the top of thedisinfecting material. As the tank fills with water the water passesthrough the port-holes 82 and elevates the float, at the same timemingling with a portion of the disinfecting material. As the float fallswith the water as it is discharged from the tank the float serves toforce the liquid outward through the port-holes 32, so as to mingle withthe larger body of water within the tank. The principle involved in themodification is the same as Where the float is arranged externally, butthe action is the reverse, as the fluid is ejected with the downwardmovement of the float, while with the internally-arranged float thefluid is ejected from the receptacle in the upward movement of saidfloat. Under both arrangements the operation is entirely automatic.

I do not desire to be limited to the details of construction andarrangement hereinabove set forth, and accordingly reserve the right tochange, modify, or vary the construction within the scope of theappended claims.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is
